There are several sites in the vicinity of Ki Jo Castle in Okayama Prefecture that are associated with the legend of Momotaro. Onino-sashiageiwa Rock is one of them.

In Kyuenji, located 3km away from Ki Jo Castle, are many granite rocks, each with a name. The most representative rock among them is Onino-sashiageiwa, which is 15m long, 5m wide and 5m thick. Usually visitors are astonished by its size. It is said that the name derives from the story that Ura, the legendary ogre, hoisted the rock up to make a shelter underneath. The crater in the rock was made when Ura lifted it. It is said that the name 'Kyuen' is derived from the shelter.
